that you can reconnect the cables correctly after the new controller canister is
reinstalled.

tray.
The display flashes a sequence of codes. To find information about the displayed
diagnostic codes, refer to Section 11.9 Things to Know – Diagnostic Code Sequences for

8. Take the controller offline, if necessary, and wait for the Controller Service Action
Allowed LED to come on.

canister.
If fiber-optic cables are present, you can use the two release levers to partially remove
the controller canister. Opening these release levers makes it easier to press down on
the fiber-optic cable release tab. If the storage array is running while you perform this
replacement, do not disturb the second controller canister.
10. Remove the failed controller canister.
– Unlock and pull out the release levers to release the controller canister.
– Using the release levers and your hands, pull the controller canister out of the
controller-drive tray.
